Product Description:

Re-dispersible polymer powder(RDP), is Vinyl acetate ethylene copolymer, also called VAE copolymer or VAE emulsion powder. It is made from VAE emulsion and use PVA as the protection colloid. RDP powder could disperse in water very well and form the emulsion fast, which is widely used in dry mix mortar industry to increase the flexibility, workability, bonding strength, water proofing, and etc.

The polymer powder is produced by spray drying a polymer dispersion. Upon contact with water, the dispersible polymer powder particles will disintegrate and release the individual dispersion particles again. The dispersed polymer powder has the same characteristics as the original dispersion.

Application

Re-dispersible polymer powder (RDP) is the main additive of dry powder ready-mixed mortar such as cement-based or gypsum-based. It has good dispersibility, high flexibility, High weather resistance, the same chemical properties as the initial emulsion.

Hecocell® RDP Polymer can be used in various dry-mixed mortars, such as internal and external wall putty , tile adhesive, tile jointing agent, dry powder interface agent, external thermal insulation mortar (ETICS/EIFS), self-leveling, repair mortar, decorative mortar, waterproof mortar, etc.

External wall insulation system;

Tile binder and joint filler;

Ceramic tile renovation and wood planking putty;

Inner and outer wall putty;

Interface mortar;

Cement-based waterproof mortar;

Repair mortar;

Self-leveling mortar;

Masonry plastering mortar.

Hecocell® advantages

Meet today's technical requirements; almost all dry-mix mortars require polymer modification. Many cement mortars contain cellulose ethers as additives to improve water retention and workability. However, after curing and drying, their adhesion will be poor. In addition, cement mortar is a very hard, fragile and inflexible material, and for many applications, flexible and deformable cement materials are essential. Therefore, for almost all applications in modern buildings, the cement mortar must be modified with polymers, Hecocell® has the following advantages：

Easy to work, easy to operate, no stickiness;

Good initial bonding strength;

Good workability, easy to spread, no stickiness;

Good sag resistance;

Good wettability for a long opening time;

It can be adjusted for a long time.

Safety Notes

The powder is pollution-free item, non-edible，once contact with eyes, wash with plenty of water asap，seek medical advice immediately if body allergic.
